co P Y STATE OF NEW JERSEY Department of Labor 571 Jersey Ave., Jersey City. June 24, 1925. Dr. Miner, Chief Chemist, Welsbach Company, Gloucester, N.J. Dear Dr. Miner: Dr. Martin Szamatolski, Ph.D., Consulting hemist for the New Jersey State Department of Labor, advised me that you are regarded as one of the leading experts in the United States on the question of the influence of mesothorium on the human body. The Department of Labor is deeply interested in this matter owing to a number of fatal cases of poisoning that occurred in a plant using a radio active luminous paint compound composed of Z nc sulphide and, perhaps, a small quantity of mesothorium. I shall deeply appreciate any information you may be able to give the department on literature regarding the influence of radio actibe compounds on the humna body. In addition, we would appreciate your advising us of any experience you may have had along these lines as a number of workers in the plant mentioned suffered severe cases of necrosis and pernicious anemia. Thanking you for any information you may be able to give us, I remain Very truly yours, (Signed) John Roach DEPUTY COMMISSIONER OF LABOR.
